Severe problem during download of Firmware makes PCI card useless

it took some time to build everything but now I have finished your 
proposed procedure and everything seems to work again! (For now I have 
just performed a short test, I'll test more tomorrow!)

So thank you very much for this excellent support! (I really was afraid 
that I couldn't use the card anymore, so I really appreciate your 
immediate help!)

Regards Ingo

PS: The compilation of the driver works also with the latest snapshot, 
I'm talking about the thread: Problem with compiling 
Thanks again!
